Apple rolled out a handy new password protection feature for its Notes app on iOS and OS X in recent updates, but it’s not super obvious how to actually use it. Here’s how to lock those notes.

On iPhone

For whatever reason, Apple’s been keen on shoving all its additional app features into the share icon on iOS, a place where most of us don’t bother tapping unless we’re actually sharing something. That’s where you’ll find the lock function:

Select a note in Apple Notes.

Tape the Share icon (the box with an arrow in the up right corner).

Tap “Lock Note.”

Type in a password and select whether you want to use Touch ID.

On OS X

Locking a note is a bit more straightforward in OS X:

Tap the Lock icon in the toolbar.

Click “Lock This Note” and enter your password.

Provided you have your notes synced with iCloud, you can lock them on one device and it’ll password protect the note everywhere.
